- Ores of reactive metals have to be heated with carbon or carbon monoxide in order to extract the metal. Carbon is a non-metal but it is more reactive than some metals. This means that some metals can be extracted from their metal oxides using carbon. This works for zinc, iron, tin, lead and copper.

The method used to extract a given metal from its ore depends upon the reactivity of the metal and how stable the ore is. In each case the metal ions in the compound gain electrons to...
Metals can be arranged in order of reactivity by observing their reactions with water, acid and displacement reactions with other metal compounds. This determines how it is extracted from its...
Both oil and water are used to separate impurities. It can only be done when the ore forms froth when compressed air is passed in this medium. The frothed ore collects on the oil section whereas the impurities settle down in the water medium.

In hydrometallurgical smelting, metals are extracted from ores using water-based solutions and chemical reactions rather than heat. Leaching is a common hydrometallurgical process where ore is dissolved in a suitable aqueous solvent to separate metals.
Concentration of ores, or ore dressing, involves converting bigger lumps of ore into smaller pieces which are more suitable for extraction. This process mainly consists of crushing and grinding followed by physical or chemical methods like washing, magnetic separation, froth floatation, or leaching.
